After boiling, the calcium in milk will appear phosphoric acid precipitation phenomenon; Thereby reducing the nutritional value of milk.

Protein in milk will change from sol state to gel state under the action of high temperature, which will lead to precipitation and reduce its nutritional value.

Do not add sugar when cooking milk, and add it after it is cooked away from the fire; Do not boil when heating, and do not cook for a long time, otherwise it will destroy nutrients and affect human absorption; The scientific method is to boil milk with big fire. When the milk is about to boil, remove it from the fire immediately and then heat it. Repeat this for 3 ~ 4 times, which can not only keep the nutritional components of milk, but also effectively kill bacteria in milk.

Generally, burnt protein can't be eaten, but your current situation is only that the bottom of the pot is a little burnt, and the milk has only a little burnt smell, so you should drink it except the burnt part of the bottom of the pot. If you don't want to pour it out, it's okay to drink it once in a while. It is suggested that you should be careful when heating milk in the future, or simply heat milk in the microwave oven so that this will not happen.

Precautions for drinking milk:

1. First of all, milk should not be eaten after frozen storage.

In life, some people buy fresh milk in bags for a week at a time for convenience, and then put it in the refrigerator to take away. In fact, it is unscientific to do so.

Frozen milk will have solidified sediment after thawing, and the floating cellulite has a light taste and peculiar smell, and the juice is watery, and its nutritional value is obviously reduced. If the storage time is too long, food hygiene problems will occur.

In addition, don't add calcium powder to milk.

Because protein in milk is mainly casein, when calcium powder is added to milk, casein will combine with calcium ions, leading to milk coagulation, and other protein in milk will precipitate with calcium when heating milk, thus affecting the absorption of nutrients.

But milk itself is rich in calcium, which is in a reasonable balance with other ingredients in milk. Under normal circumstances, there is generally no precipitation. Therefore, when eating milk, there is no need to add calcium powder.

The best time to drink milk is to drink a glass of milk before breakfast.

The calorie supply of breakfast accounts for 25%-30% of the total calorie demand, which can provide sufficient nutritional guarantee for the vitality of the day. You can also drink milk at around 4 pm before dinner 1 hour. Drinking a glass of milk before going to bed at night can also help the body absorb nutrients and play a hypnotic role.
